Potato
A single medium-sized potato contains about half the daily adult requirement of vitamin C. Other staples such as rice and wheat have none. Potato is very low in fat, with just 5 percent of the fat content of wheat, and one-fourth the calories of bread. Boiled, it has more protein than maize, and nearly twice the calcium.

Potato is the fourth most important food crop in the world, with annual production approaching 300 million tons. More than one-third of the global potato output now comes from developing countries, up from just 11 percent in the early 1960s. CIP has played an important role in this shift, providing resource-poor farmers with a range of new technologies and potato breeding lines specifically designed for developing-country conditions.

A Healthy Potato is one which grows and develops without experiencing any limiting factors that reduce quality or economic returns. Agriculture on a worldwide scale is undergoing many fundamental changes.
